I've been following https://quarkus.io/guides/kubernetes-config in order to create a configMap and test my Quarkus service into my CDK v3.5.0-1 before to push it to OpenShift 3.11 but KubernetesConfigSourceProvider is not happy:

Using:

  • Quarkus 1.8.1.Final
  • Java 11
  • CDK 3.5

Here is the yaml file I want to convert into a configMap doing: oc create configmap quarkus-service-configmap --from-file=application.yml

jaeger_endpoint: http://192.168.56.100:14268/api/traces
jaeger_sampler_manager_host_port: 192.168.56.100:14250
sql_debug: false
quarkus:
    datasource:
        db-kind: h2
        jdbc:
            detect-statement-leaks: true
            driver: io.opentracing.contrib.jdbc.TracingDriver
            enable-metrics: true
            url: jdbc:tracing:h2:./db;AUTO_SERVER=TRUE
        max-size: 13
        metrics:
            enabled: false
        password: sa
        username: sa
    flyway:
        locations: db/prod/migration
        migrate-at-start: true
    hibernate-orm:
        database:
            charset: UTF-8
            generation: none
        dialect: org.hibernate.dialect.H2Dialect
    http:
        port: 6280
    jaeger:
        enabled: true
        endpoint: ${jaeger_endpoint}
        sampler-manager-host-port: ${jaeger_sampler_manager_host_port}
        sampler-param: 1
        sampler-type: const
    resteasy:
        gzip:
            enabled: true
            max-input: 10M
    smallrye-health:
        ui:
            always-include: true
    swagger-ui:
        always-include: true

Here is the generated configMap:

  • Could you SocketTimeoutException be a coincidence, and not related to your code at all? My experience is that Quarkus can be unpredictable on Minishift. Commented Sep 21, 2020 at 20:36
  • Why not despite it happens very single time, any idea on how I could confirm that? If I: curl -k \ -H "Authorization: Bearer <Bearer> \ -H 'Accept: application/json' \ https://172.30.0.1:443/api/v1/namespaces/dci/configmaps/quarkus-service-configmap it returns immediatly. Commented Sep 21, 2020 at 22:00
  • Ok, I found that I had to configure KubernetesClientBuildConfig proxy variables, thanks @KevinBoone for puting my nose where it smelt :-) Commented Sep 21, 2020 at 23:36
